You're moving the goalposts, but are still wrong. I don't have time to dig up the references, but there are plenty of studies showing that apes (and other animals) can develop arbitrary culturally-transmitted "taboos", with violation of those taboos provoking dissent and general politicking.

We can't speak to the depths of such a debate, because we can't participate in the debate. It's an (inter-)subjective matter for the animals involved; all we can do as external observes is be objective. But this then leads us into a categorical error: because we can describe a behaviour using objective language, we therefore decide that it in fact contains no subjectivity; eg., is not truly conscious.

We used to mis-apply this logic to so-called "inferior" human cultures, denying their humanity because we couldn't get inside their minds. This was wrong, and led to great evil. Until recently, we've applied the same thinking to animals -- but it's just as wrong. There are a shrinking number of Descartian holdouts, and I guess you're one of them. But all evidence and logic is against you.
